Delivery, Deployment & Positioning

Track cardiovascular devices through complex anatomical pathways and under pulsatile conditions to identify risks such as migration or malpositioning.

In Vitro & Hydrodynamic Testing

Visualize leaflet motion, stent expansion and deployment dynamics across a range of simulated flow conditions.

In Vivo Device Tracking

Track and analyze medical devices and biological structures within living systems, including directly from DICOM images.

Material Characterization

Use 2D and 3D Digital Image Correlation to analyze deformation, strain distribution and failure mechanisms under various loading conditions.

Fatigue & Accelerated Durability

Measure cyclic motion, deformation and failure progression under simulated physiological conditions to identify failure modes early.

Soft Tissue & Biomechanics

Measure strain and elastic properties of tendons and other biological tissue under tensile load with DIC — for orthopaedic and biomechanics research.

Untitled design (41)

Two tissue layers, two different behaviours.

Researchers at the University of Pretoria used TEMA's Digital Image Correlation to measure the elastic properties of rotator cuff tissue, and found that tendinous and capsular layers respond differently under load.

About the study

Published: European Journal of Orthopaedic Surgery & Traumatology, 2025
Research team: University of Pretoria and partner institutions
Method: tensile testing of human shoulder tissue, recorded with DIC cameras
Key finding: tendinous layers showed higher average tangent elastic moduli than capsular layers

What is TEMA Medtech?

TEMA Medtech is motion analysis and measurement software for the medical technology industry. It turns high-speed video and medical images into quantified motion, deformation and strain data for in vivo and in vitro testing, material characterization and device performance validation.

What test scenarios does TEMA Medtech support?

Delivery, deployment, positioning and retraction; in vitro and hydrodynamic testing; in vivo device tracking; material and soft tissue testing with DIC; and fatigue and accelerated durability testing.

Can TEMA analyze fluoroscopy and other medical images?

Yes. The In vivo configuration includes DICOM image support, so devices and biological structures can be tracked directly in medical imaging data.

How accurate are TEMA measurements?

In synthetic test data covering image noise, compression and oblique viewing angles, trackers located the target centre with a mean error of about 0.1 px across all tested detection radii, with 99% of tracked frames within 0.42 px. At the best chosen tracker radius, mean error was 0.05–0.13 px depending on the condition, with a per-axis precision of about 0.06 px under image noise.

Errors were essentially unbiased (systematic offset below 0.05 px), normally distributed and independent of target speed, so the tracker’s measurement noise is both small and predictable.

Why should I use TEMA for my test reports?

TEMA gives you repeatable, quantified measurement data and visual evidence of device performance to include in your test reports.

Instead of relying on subjective visual inspection, you can track and measure motion directly from your test footage, such as position, velocity, acceleration and angles, with consistent results every time. The results can be exported as graphs, data tables and annotated video, so your reports show both the numbers and the visual proof behind them.

Which TEMA Medtech configuration is right for our lab?

In vivo suits device tracking in living systems and medical images; In vitro suits bench and hydrodynamic testing with 2D, 3D and 6D analysis; Material testing adds DIC surface tracking for strain and deformation. Our team can help you choose.

What cameras and hardware do we need — do we have to buy proprietary equipment?

No. TEMA supports all commonly used video and image formats and a growing range of vendor-specific codecs, so you can use your existing high-speed cameras.

How much does TEMA Medtech cost?

TEMA Medtech is available in several configurations, priced to match your test program's needs. Contact us for a quote based on your configuration.
